“The promise of quasi-infinite and free energy is here,” Lepercq declares, in an interview with Bloomberg. His arguments aren’t based on any environmental concern. Rather, he takes the perspective of price.

“Solar, battery storage, electrical and hydrogen vehicles, and connected devices are in a ‘J’ curve,” Lepercq said. “Hydrogen is the missing link in a 100 percent renewable-energy system, but technological bricks already exist.” Lepercq believes that the price of solar power will probably fall below $10 per megawatt-hour (roughly 1¢/kWh) in the world’s sunniest places.

As a consequence of the rise of renewables, oil prices are expected to plummet. “Even if oil demand continues to climb until 2025, its price could drop to $10 if markets anticipate a significant fall in demand,” he said.

“As carmakers offer more electrical vehicles with a range exceeding 500 kilometers, charging stations being progressively deployed and more cities banning gasoline and diesel cars, a shift will progressively take place,” Lepercq added.

Indeed, gone are the days when people viewed renewable energy sources as too expensive. Instead, we are moving away from conventional coal-based sources, which could even be more expensive in the future.

Solar Power Shines

Lepercq isn’t alone in seeing the price potential of renewables, particularly solar energy. The World Economic Forum (WEF) recently published a report showing how solar power now costs cheaper than fossil fuels.

[R]enewable energy technology, especially solar and wind, has made exponential gains in efficiency in recent years, enough to achieve economic competitiveness and, in an increasing number of cases, grid parity. For instance, the unsubsidized, levellized cost of electricity (LCOE) for utility scale solar photovoltaic, which was highly uncompetitive only five years ago, has declined at a 20% compounded annual rate, making it not only viable but also more attractive than coal in a wide range of countries.
